SPECIFICATION forming part of Letters Patent N 0. 680,057, dated August 6, 1901.

Application filed December 10, 1900. Serial No. 39,335. (No model.)

To all whom it may concern:

Be it known that I, THOMAS MART, a sub ject of the Queen of Great Britain, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved lVindow-Cleaner, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for cleaning or polishing windowglass, and the object is to provide a simple device by means of which a person within a room may simultaneously clean or polish both the inner and outer surfaces of the windew-glass.

I will describe a window-cleaner embodying myinvention and then point out the novel features in the appended claims;

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference in; dicate corresponding parts in both the views.

Figure 1 is a perspective view of a windowoleaner embodying my invention, and Fig. 2 is a side view showing the members spread and held apart for convenience in attaching polishing-cloths to the heads.

The cleaner comprises two opposite arms 1 2, designed to have yielding movement toward and from each other. These members 1 and 2 will be of any suitable length, and to provide for their yielding movement the lower ends are connected byaspring 3. This spring 3 is shown in the form of a plate-spring and is made U-shaped, but it is to be understood that I do not limit the invention to this particular form or shape of spring.

On the upper end of the member 1 is a headblock 4, and on the upper end of the member 2 is a head-block 5. The polishing-cloths are designed to be placed on these heads, and it will be noted that the head-block 4 is of less thickness than the head-block 5. As the head-block 5 is the wider one of the two, it is designed to engage against the inner surface of the glass, the width of the head permitting the member 2 of the device to move free of the sash projection, which is greater on the inner side than on the outer side. Polishingcloths a; are designed to be placed over the heads at and 5. As a convenient means for holding the cloths as folded around the heads I employ clips, here shown as plate-springs 6, secured at one end to the members of the cleaner and adapted to engage their free ends with the folded cloth, as clearly indicated in Fig. 2.

For holding the members 1 and 2 apart while adjusting the polishing and cleaning cloths I employ a spreader consisting of a wire loop '7, having swinging connection with one of the side members, here shown as the member 2, adapted when it is transversely between the members to engage its free end against the inner side of the opposite member, thus holding the members apart, as indicated in full lines in Fig. 2. When the device is in-use, however, this spreader is to be swung downward so that its free end passes underneath the lower end of the side member 2, and therefore the spreader will not interfere with the movements of the cleaner.

For polishing the window-glass whiting or other suitable material is to be placed on the polishing-cloths, which may be padded at the inner surface, if desired. The spring 3 will hold the cloths sufficiently tight against the opposite sides of the glass to permit of the polishing.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A window cleaner, comprising two arms or members having spring yielding connec-' tion at one end, a spreader having swinging connection with one of the members and adapted to hold the members in inoperative position, and head-blocks on the free ends of said members, substantially as specified.

2. A window-cleaner, comprising two arms or members having spring yielding connection at one end, a spreader-loop having swinging connection with one of the members and adapted to engage its free end with the op posite member for holding the members in inoperative position, head-blocks on the free ends of said members, the said head-blocks being of difierent widths, and spring-plates mounted on the members for securing cloths on the head-blocks, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS MART.
